Hybrid tea rose plant named &#39;Olijplam&#39;

ABSTRACT

A new and distinct variety of Hybrid Tea rose plant is provided which forms attractive double dark red blossoms. The plant exhibits an erect growth habit thick sterns, and dark green and very glossy roliage. Excellent disease resistance is exhibited. The new variety is particularly well suited for producing cut flowers under greenhouse growing conditions.

SUMMARY OF THE INVENTION

[0001] The new variety of Hybrid Tea rose plant was created by arificialpollination wherein two parents were crossed which previously had beenstudied in the hope that they would contribute the desiredcharacteristics. The female parent (i.e., the seed parent) of the newvariety was the ‘Pekcoujenny’ variety (United States Plant Pat. No7,749). The male parent (i.e., the pollen parent) was the ‘Ridriko’variety (U.S. Plant Pat. No. 7,362). The parentage of the new varietycan be summarized as follows:

[0002] ‘Pekcoujenny’×‘Ruidriko’.

[0003] The seeds resulting from the above pollination were sown andsmall plants were obtained which were physically and biologicallydifferent from each other. Selective study resulted in theidentification of a single plant of the new variety.

[0004] It was found that the new variety of Hybrid Tea rose plant of thepresent invention possesses the following combination ofcharacteristics:

[0005] (a) forms attractive double dark red blossoms,

[0006] (b) exhibits an erect growth habit,

[0007] (c) forms thick stems,

[0008] (d) forms dark green and very glossy foliage, and

[0009] (e) is particularly well suited for the production of cut flowersunder greenhouse growing conditions

[0010] The dark red blossoms contrast nicely with the very Mossy drkgrew foliage.

[0011] The new variety well meets the needs of the horticultual industryan exhibits good productivity during cut flower production in agreenhouse

[0012] The new variety has been found to undergo asexual propaganon inFrance by a number of routes, including budding, grafting, and cutta.Aseiual propagation by the above-mentioned techniques in France hasshown that the characteristics of the new variety are stable and arestrictly transmissible by such asemal propagation from one generation toanother.

[0013] The new variety has been named the ‘Olijplam’ varicy.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

[0014] The accompanying photograph shows as nearly true s it israsoniaby possible to make the same, in a color illustration of thischaracter, typical specimens of the plant parts of the new variety. Therose plant of the new variety were two years of age and were observedduring November while budded on Rosa indica understock and growing ingreenhouses at Le Canner des Mmres, Var, France. Dimensions incentimeters are indicated at the bottom of the photograph.

DETAILED DESCRIPTION

[0030] The chart used in the ideinfi cation of the colors is that of theRoyal Horticultural Society (R.H.S. Colour Chart). The description isbased on the observation of three year-old plants during April whilebudded on Rosa indica understock and growing indoors at Le Cannet desMaures, Var, France. The coloration in common tarms precedes referenceto the chart in some instances.
